A flat plate of width = 1m is maintained at a uniform surface temperature, Ts = 230°C, by using independently controlled, electrical strip heaters, each of which is 50 mm long. The ambient air at 25°C flows over the plate at a velocity of 60m/s. The critical Reynolds number for a flat plate is 5 x 105 To = 25°C Plate 1 Plate 5 u = 60 m/s 50mm T = 230°C insulation cony = = Beer L1 = 50mm L4 = 200mm The properties of air are given as: k = 0.047 W/mK; Pr = 0.67; v = 27 x 10-6m/s2 Calculate the local maximum heat transfer coefficient that is produced
